Accurate airway segmentation from computed tomography (CT) images is critical for planning navigation bronchoscopy and realizing a quantitative assessment of airway-related chronic obstructive pulmonary disease (COPD). Existing methods face difficulty in segmentation, particularly the small branches airway. These difficulties arise due to constraints limited labeling failure meet clinical use r...

BACKGROUND Cholinesterase inhibitor-based reversal agents, given in the absence of neuromuscular block, evoke a partial upper airway obstruction by decreasing skeletal upper airway muscle function. Sugammadex reverses neuromuscular block by encapsulating rocuronium. However, its effects on upper airway integrity and breathing are unknown. METHODS Fifty-one adult male rats were anaesthetized w...

Laryngospasm is reversible spasm of vocal cords that common in patients who are undergoing upper airway related surgeries under general anaesthesia. It occurs mostly following extubation; requires immediate management and if these left untreated rapid decrease saturation with bradycardia may take place. Lignocaine considered effective prevention laryngospasm by both topical intravenous route. a...

Objective To compare the effects of saddle, lumbar epidural and caudal blocks on anal sphincter tone using anorectal manometry. Methods Patients undergoing elective anorectal surgery with regional anaesthesia were divided randomly into three groups and received a saddle (SD), lumbar epidural (LE), or caudal (CD) block. Anorectal manometry was performed before and 30 min after each regional bloc...

We evaluated the efficacy of local or systemic parecoxib combined with lidocaine/clonidine IV regional analgesia in complex regional pain syndrome (CRPS) type 1 in a dominant upper limb. Thirty patients with CRPS type 1 were divided into three groups. The control group (CG) received both IV saline in the healthy limb and IV loco-regional 1 mg/kg of lidocaine + 30 mug of clonidine, diluted to a ...

Background: There are different anesthetic techniques for AVF (Arterio-venous fistula) creation as general anesthesia, regional anesthesia and local anesthetic infiltration. Sympathetic nerve block is produced by regional anesthesia which increases intraoperative venous diameter and vessel flow, both intra-operatively and for several hours post-operatively. Regional anesthesia can maintain adeq...
